Polyaspartic Floor Coating in Amarillo, TX
Polyaspartic floor coating is a two-part, fast-curing coating that Laticrete defines as an "aliphatic polyurea", and in Amarillo its chief value is the cold end of its application range. Citadel's comparison table rates its polyaspartic grout coat for use from 0 degrees F to beyond 90 degrees F, its polyurea base coat from 30 degrees F to 140 degrees F, and epoxy only above 50 degrees F. The Amarillo airport's daily minimum sinks to 32 degrees F or below on 107.9 days in a normal year, by NOAA's 1991-2020 normals. That station logs outdoor air, not a slab, so a thermometer on the concrete and a dew point reading come before any mixing. Below are the chemistry in the makers' words, the limits, sunlight, cure speed and prices; the slower epoxy flake system is on our garage floor epoxy page.
HomeGuide's surveys put polyaspartic a step above epoxy. Its November 2024 polyaspartic report gives $5 to $12 per square foot installed, national, against $4 to $10 for epoxy, and by garage: 1-car garages (288 to 392 square feet) run $1,400 to $4,700, 2-car garages (400 to 576) $2,000 to $6,900 and 3-car garages (576 to 864) $2,900 to $10,400. Of that rate, HomeGuide assigns $2 to $6 to materials and $3 to $6 to labor, per square foot. Flakes, custom colors or patterns add $0.50 to $2.00 a square foot; moisture and hardness tests, $50 to $300. HomeGuide's September 2025 polyurea page puts that chemistry at $5 to $10 per square foot. All of it is national, and no survey we cite prices Amarillo. Our coating cost tables set these beside the epoxy rows.
A polyaspartic floor is usually built from more than one product. Citadel, a Rust-Oleum brand, puts the polyaspartic on top of an epoxy or polyurea base "to deliver rapid curing, UV stability, and enhanced chemical resistance." Its Polyurea-350 base coat, per technical data CDL-11, is 98 percent solids and builds 5 to 20 mils of dry film, and CDL-15 gives ET-80, an 80 percent solids polyaspartic, 6 to 12 mils dry per coat from 7.5 to 15 mils wet. Laticrete's data sheet DS-864-0822 calls Spartacote Flex SB self-priming and caps a single coat at 10 mils wet. In Laticrete's chip guideline, TDS 432, a 4 mil pigmented coat takes the broadcast chips and one clear coat at 160 square feet per gallon seals them. Concrete Decor magazine notes that polyaspartics "perform at thinner applications and aren't self-leveling like epoxies."
A fast cure buys no tolerance for a wet slab. Laticrete's sheet for Spartacote Flex SB states "The RH of the slab must not exceed 75% as tested per ASTM F2170," a tighter probe limit than the 85 percent Sika allows its Sikafloor-264 epoxy, and Laticrete's quartz guideline caps the calcium chloride result under ASTM F1869 at "3 lbs./1,000 ft2/24 hrs." Laticrete also warns that polyaspartics "will not breathe and can exhibit moisture challenges over time if not used properly." Citadel's comparison table marks its polyurea base coat, like epoxy, "Not intended for MVT resistance/damp concrete application," MVT being moisture vapor moving up through the slab. For profile, the quartz guideline asks for CSP-2 from diamond grinding at 30 to 100 grit, and since "Flaws or obvious repairs in the underlying floors will be reflected," in Concrete Decor's words, patches are ground flat first.
Speed is the point of the chemistry, and the sheets print it at room conditions. Laticrete gives Spartacote Flex SB foot traffic in 2 to 4 hours, vehicles in 24 hours and a recoat window that opens after 1 to 2 hours and shuts at 24, all "based on 70 degrees F & 50% RH." Citadel's ET-80 opens to foot traffic at 2 to 4 hours and to cars at 24, at 70 to 80 degrees F, and reaches full cure at 7 days, and its Polyurea-350 base must be sanded if the 12-hour recoat time passes. HomeGuide's December 2024 garage survey says polyaspartic coatings "can often be installed and fully cured within 1 day, though some jobs require 2 days." Cold stretches these times, so your written traffic times come from the sheet at your slab's temperature. Clear the floor before the crew arrives, and afterward keep water off as the sheet directs, which for Westcoat's EC-101 means 48 hours.
A written quote for a polyaspartic floor rests on slab readings, so it comes after a visit. We measure, test the slab by the method on the chosen product's sheet, note cracks, joints and old coatings, and ask when the floor has to be back in use. The quote names the base and top products, the order of coats, the dates and the price, spells out inclusions and exclusions, and lists a moisture-mitigating primer as its own item whenever the test readings require one. The Texas Department of Licensing and Regulation's list of regulated programs includes no flooring, coating or painting program, so the checks worth asking any installer for are the data sheets and the test results. Ask for a free written quote with a rough size and two or three photos.
When polyaspartic is the right call for your floor
Polyaspartic earns its higher price when time or temperature rules out a slow epoxy cure, or when sunlight reaches the floor. Most of these conditions can be judged from the driveway before anyone tests the slab, and the slab tests still decide.
- The work lands in freeze season: in NWS Amarillo's 1892-2025 freeze study, 49 percent of first fall freezes came on or before October 26.
- The car or shop truck has to be back on the floor within a day or two, not after the days an epoxy sheet gives at 50 degrees F.
- Sunlight falls on the slab through a raised door or a window, where Sika says its Sikafloor-264 epoxy will discolor and Laticrete calls most polyaspartics UV stable.
- The slab reads 75 percent relative humidity or less on ASTM F2170 probes, the limit Laticrete sets for Spartacote Flex SB.
- The concrete is sound and close to flat, because a thin polyaspartic film reflects flaws and repairs instead of leveling over them.
If the slab reads wetter than the sheet allows, a fast cure does not change that; the fix is a moisture-mitigating primer and a system its maker rates over it. If the slab is badly cracked or uneven, an epoxy base under a polyaspartic top is one of the options below.
Application ranges on the sheets against Amarillo's freezing nights
Most polyaspartic and polyurea sheets in our sources allow application well below the 50 degrees F that Citadel's table sets for epoxy, though the makers that address it say cold slows the cure. Citadel's Polyurea-350 sheet allows 0 to 90 degrees F and its RG-80X topcoat 30 to 90 degrees F, while Laticrete claims a low-temperature cure to 25 degrees F for Spartacote Flex Pure and to -30 degrees F for Flex SB. Not every polyaspartic is a cold product: Westcoat's EC-101 may not go down below 50 degrees F, and Dur-A-Flex recommends applying Accelera between 60 and 85 degrees F. The cold season here is long. For the Amarillo airport, NOAA's 1991-2020 normals count days on which the daily low reaches 32 degrees F or below: 14.7 in an average November, 26.3 in December, 26.7 in January, 21.2 in February and 12.6 in March.
Highs stay at or below 32 degrees F on 9.1 days a year, and lows fall to 0 degrees F or below on 0.5. Set beside those normals, a topcoat rated down to 30 degrees F still sits above the average outdoor lows for December, January and February, 25.7, 24.9 and 27.5 degrees F, while one rated to 0 degrees F meets air that cold on 0.5 days a year. The station reads outdoor air, not your slab, and Citadel and Sherwin-Williams both say colder conditions lengthen the cure; the 24-hour vehicle times on these sheets are stated at 70 degrees F or a little above. Our Panhandle floor weather guide compares the freeze dates by source.
Humidity, dew point and dry Panhandle air during a fast cure
Humidity speeds or slows a polyaspartic, and the makers print limits at both ends. Westcoat writes of its EC-101 that "High humidity will reduce the working time and dry time. Low humidity will increase dry time." Laticrete says rising temperature or humidity shortens the working time, dry time and recoat window of Spartacote Flex Pure, and warns against mixing below the dew point. At the dry end, Sherwin-Williams does not recommend its fast-cure Accelera below 30 percent jobsite relative humidity and offers a low-humidity resin for 10 to 30 percent. At the damp end, Citadel caps RG-80X at 75 percent and Polyurea-350 at 85 percent and asks for 5 degrees F of margin between the surface and the dew point.
NOAA's 1991-2020 hourly normals for the Amarillo airport show how far apart air and dew point run. The January 15 dew point averages 19.7 degrees F at 06:00 and 21.0 degrees F at 15:00, while the air averages 29.5 and 49.7 degrees F at those hours; on July 15 the dew point averages 58.9 degrees F at 06:00 with the air at 67.8 degrees F, a gap of 8.9 degrees F by our subtraction. Our sources hold no relative humidity figure for Amarillo, so the air, the slab and the dew point are measured on site before mixing, and the product is matched to those readings. The Amarillo floor numbers page gives the hourly dew points.
Sunlight and color: aliphatic polyaspartic against epoxy
Polyaspartic holds its color in sunlight better than standard epoxy, by the makers' own accounts of both. Concrete Decor magazine describes polyaspartic esters as resins for "two-component light-stable coatings" whose UV stability "prevents yellowing and material degradation in outdoor applications," and Laticrete says most polyaspartics are UV stable and suitable outdoors. Epoxy makers say the reverse of their own products: Sherwin-Williams writes that "Epoxy coatings may darken or yellow following application and curing," Sika that Sikafloor-264 "Will discolor over time when exposed to sunlight (UV)," and Westcoat restricts its EC-36 epoxy to interiors unless a UV-resistant coat protects it. Sherwin-Williams adds that making an epoxy fast-curing harms its light stability and color retention, and Citadel's table marks epoxy "No" for UV resistance.
Citadel's layering follows from this: the polyaspartic goes on top, where the light lands. The claims have limits. Westcoat says extended UV exposure may still alter the appearance and performance of its EC-101, Concrete Decor names delamination as a common failure of poorly blended polyaspartics, and Laticrete rules Flex SB out where thermal shock is continual. Torginol adds that the coating system, not the flake, decides whether a chip floor suits outdoor use.
Full polyaspartic, polyurea base or epoxy base
The choice here is what sits under the polyaspartic topcoat. Citadel assigns polyaspartic to the top of a system, over an epoxy or polyurea base, and each base brings its own temperature limit, cure speed and grip on the slab.
Polyaspartic from primer to topcoat
A self-priming polyaspartic such as Laticrete's Spartacote Flex SB goes straight onto ground concrete, with chips broadcast into a pigmented coat and a clear coat above them. Laticrete claims a low-temperature cure to -30 degrees F and hot-tire resistance for Flex SB, and calls all its Spartacote Flex coatings completely UV stable. It suits a flat, sound slab and a cold-month date, accepting thin coats that hide little.
Polyurea base, polyaspartic topcoat
Citadel's sheet lets the Polyurea-350 base go down "between 0-90 degrees F" with relative humidity no higher than 85 percent, while RG-80X, the topcoat, wants 30 to 90 degrees F and humidity under 75 percent; both sheets want a 5 degrees F margin over the dew point. Sherwin-Williams notes that polyurea stretches well but generally adheres less well than epoxy. It suits a cold job that has to finish fast.
Epoxy base, polyaspartic topcoat
An epoxy base under a polyaspartic clear coat pairs epoxy's working time and build with a light-stable top. Citadel calls epoxy "a durable, high-adhesion base layer that anchors the flooring system," but its table wants more than 50 degrees F for it, and its chip specification holds room and floor "at 60 degrees F (15 degrees C) or above" for 72 hours ahead of the install, during it and after. It suits a patched slab in a warm month.
We choose among these after the slab tests and the temperature reading, and the quote names a product for each layer. In a warm month on a sound slab, an all-epoxy flake floor stays the slower and, on HomeGuide's figures, lower-priced route.
Polyaspartic Floor Coating FAQs
What's better than epoxy for garage floors?
Neither wins outright: polyaspartic leads epoxy on cure speed, cold-weather application and sunlight, and epoxy leads on price, build and covering a rough slab. Citadel's table gives polyaspartic a 24-hour return to service against 36 to 48 hours for epoxy, and an application range down to 0 degrees F against more than 50 degrees F for epoxy. HomeGuide's November 2024 comparison lists $5 to $12 per square foot for polyaspartic and $4 to $10 for epoxy, both national. Many floors use both, an epoxy base under a polyaspartic top. Garage floor tiles are a third route, at $2 to $5 per square foot installed yourself in HomeGuide's national December 2024 survey.
How soon can I drive on a polyaspartic garage floor?
Most polyaspartic and polyurea sheets give vehicles 24 hours at about 70 degrees F, and more on a cold slab. Laticrete lists 24 hours for Spartacote Flex SB, Citadel 24 hours for ET-80 and RG-80X, and Laticrete's chip guideline asks for 24 hours out of service. Westcoat's EC-101 is slower, at 72 hours. An epoxy such as Sikafloor-264, by contrast, takes about 3 days at 50 degrees F before even light traffic. The vehicle time we write down comes from the sheet and the reading on your slab, not the room-temperature column alone.
Is polyaspartic the same as polyurea?
Polyaspartic is a type of polyurea. Laticrete's FAQ says the term refers to an "aliphatic polyurea" and that polyaspartics are often viewed as a variation of polyurea coating. A July 2024 PCI Magazine article explains that these polymers form when a diamine reacts with a polyisocyanate, and Covestro, which makes the aspartic resins, describes its systems as two-component coatings built on aliphatic polyisocyanates and aspartic resins. On a floor the difference shows in the sheets: Citadel uses a polyurea as the fast base coat and a polyaspartic as the clear topcoat, and rates the polyurea's flexibility high and the polyaspartic's moderate.
Is polyaspartic floor coating a do-it-yourself job?
Not by the makers' or the surveys' account. Concrete Decor magazine says, "This is not a do-it-yourself product," and HomeGuide's November 2024 comparison table marks polyaspartic "No" for DIY-friendly against "Yes" for epoxy. The clock is the reason: Laticrete gives Spartacote Flex Pure 10 to 15 minutes of working time, and Sherwin-Williams tells Accelera installers to lay out sections that can be finished full width in 5 minutes or less. A water-based epoxy kit gives far longer; Rust-Oleum allows 2 hours after mixing at 60 to 70 degrees F for its EpoxyShield garage kit.
